The derailment was near the bottom of the hill, right after where skiers jump on the lift, Green told ABC News, saying that the incident could have been much worse if the malfunction had been further up the hill where the lift reaches up to 60 feet.

Timberline tweeted at 10:40 a.m. that the Thunderstruck triple lift was not operating, saying that “we do not have all details at this time and our immediate focus is on our skiers.”
